Help: Do Subwoofer Cables make a difference in Sub Sound?

absolutely!

i have a dedicated Siltech subwoofer cable called "The Abyss". When i installed it i had to turn down the sub level it was that profound.

one of the best if not the best cable upgrades I've ever had

I heard obvious improvement when I went from an old spare cable to Kimber Hero cables from a recommendation. Better definition and focus. I will say, that the degree of what you may hear is dependent on your system. Sources, preamp, etc.. I also discovered that isolating my subs from my floor had the most profound improvement. But, that's my subs, my floor.

When i had my Velodyne HGS 18 sub cables made a big difference

Yes! A thing called cable subrogation comes in play! Subrogation is efficiency of cable to transmit without degradation of signal integrity! Monster is biggest bang for buck! A cable costing more than the sub provides more psychological improvement than anything!
